The AD8079 features a unique transimpedance linearization

circuitry. This allows it to drive video loads with excellent differ-

ential gain and phase performance of 0.01% and 0.02° on only

50 mW of power per amplifier. It features gain flatness of 0.1 dB

to 50 MHz. This makes the AD8079 ideal for professional video

electronics such as cameras and video switchers.

The AD8079 offers low power of 5 mA/amplifier (V_S= ±5 V)

and can run on a single +12 V power supply while delivering

over 70 mA of load current. All of this is offered in a small 8-pin

SOIC package. These features make this amplifier ideal for por-

table and battery powered applications where size and power are

critical.

Available in Small 8-Pin SOIC

APPLICATIONS

Differential A-to-D Driver

Video Line Driver

Differential Line Driver

Professional Cameras

Video Switchers

The outstanding bandwidth of 260 MHz along with 800 V/µs of

slew rate make the AD8079 useful in many general purpose high

speed applications where dual power supplies of ±3 V to ±6 V

are required.

The AD8079 is available in the industrial temperature range of

–40°C to +85°C.

PRODUCT DESCRIPTION

The AD8079 is a dual, low power, high speed buffer designed

to operate on ±5 V supplies. The AD8079’s pinout offers excel-

lent input and output isolation compared to the traditional dual

amplifier pin configuration. With two ac ground pins separating

both the inputs and outputs, the AD8079 achieves very low

crosstalk of less than –70 dB at 5 MHz.

Additionally, the AD8079 contains gain setting resistors factory

set at G = +2.0 (A grade) or Gain = +2.2 (B grade) allowing

circuit configurations with minimal external components. The

B grade gain of +2.2 compensates for gain loss through a system

by providing a single-point trim. Using active laser trimming of

these resistors, the AD8079 guarantees tight control of gain and

channel-channel gain matching. With its performance and con-

figuration, the AD8079 is well suited for driving differential
